EXCLUSIVELY FOR RENTAL, CONSTRUCTION AND MINING FLEETS

Battery and hybrid temporary power systems, specified for reality.

Crestline ensures new power systems earn their keep before fleets scale.

Start How we work

SPECIFICATION

Define the real operating problem — load behaviour, environmental extremes, and failure modes — before selecting or designing technology.

COMMERCIAL FIT

Evaluate whether the system strengthens utilisation, margin, and service capability across the fleet — not just on a single site.

FIELD ASSURANCE

Confirm that control behaviour, environmental exposure, and operator variability will not erode performance at scale.

Deployment Reality

Most deployment failures don’t begin in hardware. They begin in assumptions — about control logic, utilisation, integration responsibility, and field readiness. What performs in pilot conditions often breaks under fleet scale.

WHAT GETS PROTECTED

Decisions that can be defended.
Fleet utilisation and operability.
Support burden, spares, and field reliability.

How Crestline works

Engagements are structured. The aim is simple: reduce stranded assets while improving utilisation.

FILTER

Identify where a new category can win, and where it will quietly fail.

SPECIFY

Define requirements that align OEMs, integrators, and fleet teams.

VALIDATE

Design pilots with success measures that translate to procurement.

ASSURE

Review delivery and early performance to stop avoidable support blowouts.

Selected initiatives

Selected engagements demonstrating Crestline’s work at control, commercial, and fleet-deployment level.

CONTROL-LAYER HYBRID STABILITY (DGD)

Architecture developed within OEM functional specification work to prevent generator–battery instability under real rental conditions.

Addresses charge overload, degraded genset response, and variable operator behaviour — reducing silent failure cascades before fleet scale.

Currently in structured development discussion with OEM partners toward firmware-level implementation.

DISTRIBUTED SITE HYBRID ARCHITECTURE

Commercial and technical model developed for contractors facing decarbonisation mandates under strict cost constraints.

Combines solar, battery, and behavioural load management to deliver emissions reduction without premium site cost.

Structured for deployment within rental and construction fleet realities.

OEM SPECIFICATION AND ARCHITECTURE DEVELOPMENT

Functional specification and full-system architecture development for rental-grade BESS and hybrid platforms.

Developed as part of a 60 kW / 120 kWh rental-grade BESS platform architecture — defining mechanical, electrical, control, thermal and economic design constraints from first principles.

Enabled OEM to build proprietary products rather than rebrand imports, grounded in field reliability, IP control, and real deployment conditions.

Leadership

CRAIG SKIPSEY

Managing Partner

Craig works at the intersection of economics, technology and on-site operations — helping fleet operators make investment decisions that withstand scrutiny.

Experience spans hybrid and battery deployments, system architecture, functional specification, and commercial pilot development across the rental, construction and mining context.

Practical clarity for complex problems.

COLLABORATION MODEL

Crestline collaborates with specialist engineering and controls partners where required — while remaining independent in recommendations and decision framing.

TYPICAL TRIGGERS

Capital decisions approaching procurement or tender.
Pilot design before scaling a fleet category.
Board or exec scrutiny on ROI, utilisation and support burden.
Deployment complexity increasing beyond internal capability.
